Charles,
There are several places the query can be extended. I think you may want to
look at modifyOp() and eval() in QueryEngine (I used QueryEngineMain and
over rode those methods).
The other piece of the puzzle is to create a QueryEngineFactory that will
create your QueryEngine instance on dem
I used SERVICE federation exclusively in the granatum project query engine (
www.granatum.org). In fact the only local (not federated) data was data
that allowed us to construct the federated queries across multiple
vocabularies using a "roadmap" (

I think in such case it would be better to use Parameterized SPARQL
String instead of string concatenation:

Hello Jenarators,
If I'm implementing a custom Dataset implemention (Hi, I'm implementing a
custom Dataset for MarkLogic), how would I expect
to create a QueryExecution instance?
It seems that QueryExecutionFactory.create(Query query, Dataset dataset)
should have some hope to create a specific

problem solved :)
i read name/temat/predykat/object from TextField, validate it and when
temat/obiekt be blank node i replace it for ?a/?c and it works :)
code below

Is there any documentation that describes how SERVICE federation is
implemented, what optimizations exist, is caching done and if so, how, etc?
Can anybody report on the use of SERVICE Federation in practice?
Thanks
